Roast the peppers under the oven broiler, rotating every 5 minutes, until skins are blackened all over and peppers are softened.
Transfer to a resealable bag and seal. Let the peppers steam in the bag until cool enough to handle. Remove skins and seeds. Dice and set aside.
Prepare the onion
While peppers are cooking, heat 1 tablespoon butter in a medium skillet over high heat. Add the onion and garlic and sauté, tossing regularly, until onions are soft and lightly golden.
Add the wine and cook until most of the liquid is gone. Remove from the heat and set aside.
Prepare the topping
Combine the Ritz crackers, panko breadcrumbs, parmesan, and 1/2 cup shredded Vermont white sharp cheddar cheese with 1 tablespoon melted butter in a medium bowl. Set aside.
Cook the pasta and make the sauce
Bring a large pot of water to a boil. Heat oven to 350℉ degrees.
Add the macaroni and set time to cook to al dente according to package directions.
In a medium saucepan over medium heat, heat the remaining 2 tablespoons butter. Whisk in the flour and heat until mixture starts to bubble. Reduce heat and cook roux 2 minutes.
Whisk in the milk and heat, stirring constantly, until milk starts to steam. Add the cream cheese and remaining white cheddar cheese, stirring until smooth.
Assemble casserole and bake
Add salt to the sauce and taste for seasoning. Add the onion mixture, poblano peppers, and cooked macaroni.
Pour into a 13x9 bake dish. Top with prepared cracker mixture.
Bake at 350℉ degrees for 15 minutes or until bubbly and golden on top.
